scale_y_log10_reverse — scale_y_log10

A wrapper function that provides evenly spaced ticks with scientific notation for log10 reverse transformed y-axis. This is particularly useful for volcano plots and other plots showing p-values. The function applies a log10 transformation and reverses the axis to better visualize p-values without hard transforming the data, while maintaining the original p-value scale for interpretation. This allows you to see the full range of p-values with proper scaling while keeping the original values readable.

scale_y_log10_reverse(breaks = 5, digits = 2, ...)

Arguments

breaks: Number of breaks to display (default: 5)
digits: Number of digits for scientific notation (default: 2)
...: Additional arguments passed to scale_y_continuous

Value

A ggplot2 scale object
